However, quantitative three\u2010dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited. This study applied 3D geometric morphometrics (3DGM) to characterize diaphragmatic kinematics and curvature in COPD patients compared to controls. We prospectively enrolled 126 adults: 40 COPD patients (17 bronchitis\u2010predominant, 23 emphysema\u2010predominant) and 86 asymptomatic controls. All underwent high\u2010resolution computed tomography (CT) at functional residual capacity (FRC) and total lung capacity (TLC). Diaphragmatic form was quantified using landmark and semilandmark configurations. Curvature was estimated by fitting circular arcs to the domes. Statistical comparisons included Procrustes MANOVA, principal component analysis (PCA), and non\u2010parametric tests. Centroid size (CS) was significantly larger in COPD, reflecting dome flattening at both lung volumes. Inspiratory size increment (\u0394CS) was reduced in emphysema, particularly in females. PCA showed diminished shape change between FRC and TLC in COPD, with overlapping configurations, in contrast to distinct phases in controls. PC2 highlighted flatter domes in COPD. Curvature analysis revealed significantly larger radii in COPD, especially at TLC. In COPD, the right dome was flatter than the left, whereas controls showed the opposite. The right dome retained greater curvature change, especially in emphysema. COPD patients, particularly those with emphysema and females, exhibit diaphragmatic flattening and reduced inspiratory deformation. Asymmetrical dome behavior, with preserved right dome mobility, may reflect compensatory adaptation. 3DGM offers a valuable tool for respiratory phenotyping in COPD.<\/jats:p>","DOI":"10.1002\/ar.70161","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T07:19:07Z","timestamp":1770880747000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Three\u2010dimensional geometric morphometric analysis of diaphragmatic dome motion in\n                    <scp>COPD<\/scp>\n                    patients"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0148-5666","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"L\u00f3pez\u2010Rey","sequence":"first","affiliation":[{"name":"Paleoanthropology Group, Department of Paleobiology Museo Nacional de Ciencias Naturales (MNCN\u2010CSIC)  Madrid Spain"},{"name":"Department of Biology, Faculty of Sciences Universidad Aut\u00f3noma de Madrid (UAM)  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beno\u00eet","family":"Beyer","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Anatomy, Faculty of Motor Sciences Universit\u00e9 Libre de Bruxelles (ULB)  Anderlecht Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Garc\u00eda\u2010Vargas","sequence":"additional","affiliation":[{"name":"Department of Anthropology and Human Genetics, Faculty of Sciences Univerzita Karlova  Prague Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabel","family":"Torres\u2010S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Pneumology Department, Hospital Universitario La Paz Instituto de Investigaci\u00f3n Hospital Universitario La Paz (IdiPAZ)  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Garc\u00eda\u2010R\u00edo","sequence":"additional","affiliation":[{"name":"Pneumology Department, Hospital Universitario La Paz Instituto de Investigaci\u00f3n Hospital Universitario La Paz (IdiPAZ)  Madrid Spain"},{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica en Red de Enfermedades Respiratorias Instituto de Salud Carlos III  Madrid Spain"},{"name":"Department of Medicine, Faculty of Medicine Universidad Aut\u00f3noma de Madrid  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3141-3401","authenticated-orcid":false,"given":"Markus","family":"Bastir","sequence":"additional","affiliation":[{"name":"Paleoanthropology Group, Department of Paleobiology Museo Nacional de Ciencias Naturales (MNCN\u2010CSIC)  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,11]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"crossref","unstructured":"Adams D.
